SP8852E

2·7GHz Parallel Load Professional Synthesiser

Preliminary Information

Supersedes January 1996 version, DS4237 - 1.2

DS4237 - 2.0 June 1998

TheSP8852Eisoneofafamilyofparallelloadsynthesisers

containing all the elements apart from the loop amplifier to

fabricate a PLL synthesis loop. Other parts in the series are

the SP8854E which has hard wired reference counter pro-

gramming and requires only a single 16-bit programming

word, and the SP8855E which is fully programmable using

hard wired links or switches.

The SP8852E is programmed using a 16-bit parallel data

bus. Datacanbestoredinoneoftwointernalbuffers, selected

by a single address bit on the input interface. In order to fully

program the device, two 16-bit words are required, one to

select the RF division ratio (A and M counters) and phase

detector gain, and one to set the 10-bit reference divider

count, phase detector state and sense. Once the reference

divide ratio has been set, frequency changes can be made by

a single 16-bit data load entry to the RF divider chain.
